Discredited Stem Cells Created by Virgin Birth

In 2004, Korean investigators lead by Woo Suk Hwang at Seoul National University announced the creation of the world’s first human embryonic stem cell line generated by somatic cell nuclear transfer (SCNT), which involves the transfer of DNA, usually from a skin cell, into an egg cell that has had its DNA-containing nucleus removed. The work, published in the prominent journal Science, was retracted in 2006 amidst evidence that the researchers had falsified their data.

Development is triggered spontaneously from the egg alone without the need for sperm fertilization.
